adjustable baflie This invention relates to ventilators for windows and the like. I I My invention .is particularly directed to adjustable ventilators :for windows and the like formed of two or more mutually tele-.

scoping members having spaced baflied elements to enable the ventilator to b'ereadily positioned and removed from locked-position relative to the frame .of the windowand the like, and also to afi'ord'the'employment. of standard sizes for varied ranges of widths of window frames.

invention, the ventilator is formedofa pair of oppositely disposed members,'telescopically inter-fitting one another at the center at, their top and'bottom elements and their in-' termediatespaced baffle elements, the members at their extreme sides being notched to a be received and locked between the parting strips of the window frame, to thereby enable the window, usually the lower sash, to be brought into engagement withthe' ventilator, and locked if desired. 7

Other features and objects of my invention will be more fully understood from the following detail description and the accompanying drawings, in which Fig. 1 is an elevational view of a portion of a window, as viewed from the interior,

. and a ventilator embodying my invention po-' sitioned within the window frame;

Fig.2 is a sectional elevation on the line 2-2, of Fig. 1;

Fig. 3 's a sectional 38, of'Fig; 1, and

Fig.1 4 is an elevational view showing a modification. i

Referring to Figs. 1, 2 and 3, my venti'la-' tor is illustrated as comprising the opposite-v ly disposed member 10,11. The member 10, shown to the left in Fig. 1, includes a vertical upright element'12, preferably dimenelevation on the line sioned to be received within the inner and middle. parting strips 13, 14, of a window frame 15. The member 10 further comprises the top element 16 secured at one end ofthe vertical element 12, and further comprises the lower element 17 secured at one end to the bottom of the vertical element 12. The memanother as viewed from the exterior of the'ventilator, such" downward incllnation being "advantamolding either of metalor other suitable ma- I their upper ends to the top and bottom ele-' windowframaand for removing the same ber 12 comprises, further the intermediate bafile elements 18,-which are spaced from one and preferably downwardly inclined geous for sheddingrain and 'the'like from either directly or indirectly entering through the "ventilator; Also, asappears in F ig. 2, the outer fac'e 16 of the upper element-16 is downwardly inclined, and similarly the .60 outer face 17-of thebottom element 17 is v similarly. downwardly inclined. Persuant to a most preferred form of my shown to theright in Fig. 1, is constituted individual elements similar to the aforesaid 166 The'othe'r-member- 11, in this instance, of

parts are designated by like =ber 10,1 and like reference numbers withthe sufiix a;

{ JMy'invention is capable ofbeing formed of Y pressed-metal parts respectively shaped as E is illustrated in the drawings and otherwise disclosed herein; if desired, the constituent members of my inventionmay be formed by terial. g In the production, shipment and storage of ventilators embodying. my invention, it is desirable to collapse the members 10, 11, to full -telescopedrelationship.

For larger size ventilators, and

enforcing the intermediate portions of the "top, bottom and baflle elements,-I provide the verticalv strips 20, 21' respectively secured at men'ts 16, 17 and intermediately to therespective baffle elements 18. 'By such vertical strips, also, 'the respec tive members 10, 11,

may be readilygrasped toposition theventilator' members injproperfrelation to the so therefrom and for collapsing for storage purposesqm V From the above it'wi'llbe observed that'my invention is readily adapted for manufacture in large quantities either in the form of shaped metal partswhich are welded or otherwise suitably secured .to one another as hereinabove set forth, or cast to proper shape as mating entities, thereby resulting in a ventilator construction capable of adjustment for various standard sizes Within the range of telescoping relation of the mating members.

Whereas I have described my invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made. without departing from the spirit of the invention.

What I claim is:

1. A ventilator comprising a pair of mat ing members,

ing a vertical side element, and further including top and bottom horizontally extendof said top extending eleing elements, each ments being formed to have a portion of its upper face substantially horizontal and a further portion of its top face inclined clown- Wardly, each of said members further includeach of said members includelements and disposed intermediate the sides of said member.

In testimony whereof I have signed this specification this 20th day of June, 1928.
